Governor Christie and state Sen. Barbara Buono attacked each other for their handling of the state’s economy in dueling attack ads released Wednesday.

Buono’s ad, her first spot for television, criticizes Christie for New Jersey’s unemployment rate.

“To hear Governor Christie tell it, everything in New Jersey’s going just fine,” Buono says in the ad. “Well, I see another New Jersey, with 400,000 unemployed.”

Buono, D-Middlesex, is expected to be Christie’s Democratic opponent in this year’s gubernatorial election. In her new 30-second spot, she also says New Jersey has seen ”soaring property taxes” and “rising tuition” on Christie’s watch.

Despite struggling with low fundraising, Buono’s campaign said it spent more than $1 million on air time for the ad, which will appear on New York City network and cable channels. This is her first television ad, although she previously released online-only advertisements.

Christie’s new ad — his third for television — continues the message from his previous attack ad, trying to link Buono to Jon Corzine, New Jersey’s last Democratic governor. The Democrat was chairwoman of the Senate Budget Committee during Corzine’s tenure.

“Jon Corzine elected governor, teams up with Barbara Buono. $1.2 billion sales tax increase passed,” the narrator in Christie’s latest ad says. “After Buono named budget chair, taxes and fees increase 23 times in just two years,” the voice-over adds.

Both campaigns have also benefited from so-called issue advocacy groups, which cannot directly coordinate their actions with the campaigns but are free to raise money without disclosing their donors. One New Jersey, a group that supports Buono, has already spent more than $1 million on two ads attacking Christie. A pro-Christie group called Committee for Our Children’s Future has also spent millions on advertisements in the last two years promoting the governor’s accomplishments.
